I am using the HMC739 and setting the VTUNE to 2 is to get 24GHz. I have the output of this going to the mixer. The mixer is mixing in a signal and is send to an SMA connector that I have an antenna attached to.
According to the HMC datasheet of the HMC739, I should expect a 11dBm 24GHz signal (or close to it) go into the mixer.
According to the HMC733 datasheet it has a 9dBm insertion lose, so I should expect a 3dBm signal out the transmit antenna.
I seem to be getting a -22dBm signal instead of the 3dBm one. Have you seen this before? Any idea what would cause such a loss?
